A method and formulation are provided for the treatment of medical conditions associated with the formation and/or deposition of macromolecular aggregates, particularly those associated with adverse ocular conditions. The formulation contains a non-cytotoxic chelating agent containing at least three negatively charged chelating atoms and a charge-masking agent containing at least one polar group and having a molecular weight of less than about 250, wherein the polar group contains at least one and preferably at least two heteroatoms having a Pauling electronegativity greater than about 3.00, and further wherein the molar ratio of the charge-masking agent to the chelating agent is sufficient to ensure that substantially all negatively charged chelating atoms are associated with a heteroatom on the charge-masking agent.
本发明提供了一种方法和制剂,用于治疗与大分子聚集体的形成和/或沉积有关的病症,特别是与眼部不良状况有关的病症。该制剂含有至少三个带负电荷的螯合原子的无细胞毒性
螯合剂和含有至少一个极性基团且分子量小于约 250 的电荷掩蔽剂,其中极性基团含有至少一个,最好是至少两个保灵电负性大于约 3 的杂原子。00,其中电荷掩蔽剂与
螯合剂的摩尔比足以确保基本上所有带负电荷的螯合原子都与电荷掩蔽剂上的杂原子相连。
